The discussion then moved over to linux-input mailing list were it got fully resolved by hid-multitouch developer. A fix will be in Linux 3.3 (its in a hid next branch). The fix is slightly larger than adding new product ID's to hid-multitouch. The touchscreen uses a "MT serial" protocol that happened to be added to hid-multitouch for another touchscreen in November timeframe as well. This version of eGalax touchscreen makes use of that new feature in hid-multitouch.
